INTRODUCTION
1.3 Green PC Power Management
The Green PC mode is a state that minimizes the power consumption. Through the BIOS setting of the
PT-429G can slow down the CPU clock to 8 MHz in Green PC mode. The PT-429G extends the Green PC
feature to four external devices (Green AUX #l to # 4) by the AUX Green connector (J7 & JP32). The
Green PC mode option of these Green AUX connectors are :
- Remove the sync signals from the video monitor,
- Turn off video monitor power,
- Turn off printer power,
- Turn off hard disk drive
PT-429G will be placed into Green PC mode as a result of one of the following events :
- Power save button (GJl) is shorted.
- Expiration of one of five independent Green PC Timers, the 1st timer is used to slow down CPU
speed. The Green PC Timers are software programmable which can configured in the "Power
Management Setup!' option of the BIOS CMOS setup. (Refer to 5.8 Power Management Setup)
- Execution of the system hot key for power down sequencing <CTRL> <ALT> <\>.
Through the system activity monitoring and management, the PT-429G will not go into Green PC mode
(or leaves Green PC mode and back to normal mode) if any activity is detected on the following signals:
- IRQ1 (Keyboard)
- IRQ3 (COM2)
- IRQ4 (COMl)
- IRQ6 (FDD)
- IRQ7 (LPTl)
- IRQ14 (HDD)

ECO PAD
This external device connects to the second unique PT-429G connector to add on/off switching to
peripherals such as printers, monitors and scanners - All timing and on/off controlled by the PT429G
mother-board. Utilizing a Zero Voltage Protection Circuit the ECO PAD ensures safe and reliable on/off
switching which will not harm your peripherals.
Testing results have shown that a system using the above products consumes only 17.6 watts of power at peak
voltage of 220v.
The effective watts RMS) is less than 10
and this covers your system, monitor, printer and scanner.
Alternative system packages.
The PT429G mother-board is equipped with two unique green connectors, however it can also use
conventional VGA cards to add power saving features to monitors using their respective software driver(s). All
efforts are made to ensure the PT429G is compatible with a wide range of add-on cards.
